Specification of Letters Patent.

Patented'July 27, 1909.

Application filed March 11, 1908. Serial No.-420,378.

To all whom it may concern:

Be it known that I, HEATON I-I. WRIGHT, a citizen of the United States,residing at l/Vest Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement inFountain-Pens; and I do hereby declare the following, when taken inconnection with the accompanying drawings, and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,

and represent, -in

Figure 1 a view in elevation of a pen constructed in accordance with myinvention, its pen-cap being removed and shown in section. Fig. 2 a viewshowing the-pen (with its pen-cap removed) applied to a cork formed inaccordance with my invention and located in a small ink bottle. Fig. 3 aview showing the ink bottle upside down, with the pen in it, preparatoryto filling the pen. Fig. 4 .adetached view in elevation of the cork.Fig. 5 a plan View thereof. Fi 6 a sectional view of one of the modifiedforms which the cork may assume. My invention relates to an improvedfountain-pen and to an ink-bottle cork for use in filling the same, theobject being to produce a simple, cheap, convenient and effective penhaving few parts and adapted to hold a relatively large quantity of inkand to provide an ink-bottle cork which not only permits the pen to bereadily filled from any ordinary ink-bottle, but also provides forwashing the pen proper at the same time.

\Vith these ends in view my invention con-v sists in a fountain pen anda filling-cork therefor, the said pen and cork having certain details ofconstruction as will be hereinafter described and pointed out in theclaim.

In carrying out my invention as herein shown, I provide the body 2 ofthe pen at its forward end with an enlargement 3 which also forms thepen-holder though this is not essential. The said enlargement 3 resultsin the production at its inner end or base of a constriction 3 where itmerges into the said body, the said constriction constituting areduction of the body and enlargement in diameter below the greatestdiameter of their contiguous portions. The said body 2 is made of hardrubber or equivalent material and provided at its upper end with a shortprotected by an ink-sack cap 5 fitting over the outer end of thebodywhich is for this purpose reduced to form a sleeve 6. At its forward endthe said body is provided with external screw threads. 7 for co-actionwith the internal screw threads 8 of a pen-cap 9 a trifle larger indiameter than the body 3 and provided for inclosing and protecting thepen 10.

In conjunction with such a pen as above made in one piece and comprisinga body 11, a flange l2 and a nipple 13, the latter being formed with apen-receiving hole 14 a trifle smaller in diameter than the largestportion of the enlargement 3. Normally the hole 1-1 will be left open,As it is relatively small in area the evaporation of the ink on accountof this exposure will be so small that it may be ignored. The body 11.0fthe cork will be adapted in size to fit any standard ink-bottle in whichmy improved cork will be used just as any cork is used except when itspenreceiving hole 14 is brought into play for filling a fountain-pen.

WVhen it is desired to fill the pen, the penproper 10 and enlargement 3are inserted into the nipple 13 of the cork throu h the hole 14. Onaccount of its form t e enlargement 3 will stretch the rubbersurrounding the hole 14 sufficiently to permit the enlargement 3 to passentirely into the nipple after which the flexible edges of the rubberwill recover and form an ink-tight joint, either around the smallerupper portion of the enlargement 3 as shown in Fig. 2 or around thelower end of the body 2 where the same merges into the said onlargement3 as shown in Fig. 3 of the drawings. In either event the rubber inrecovering, enters the constriction 3 in such a way as to prevent the enfrom longitudinal movement in either irection unless suflicient force isapplied to it in the longitudinal direction to cause the'rubber edge tostretch and ride out of. the constriction. The inkbottle is thenreversed as shown in Fig. 3, causingthe ink to flow down into the body11 and nipple 13 of the cork. The ink-sack forced upward through theink. Vhen pressure is removed from the sack, ink will rush in throughthe pen 10 and enlargement 3 and take the place of the air thusexpelled. This operation is repeated until the body 2 and sack 4 havebeen entirely filled with ink.

is now squeezed to expel the air which is described, Iemploy a flexiblepen-filling cork Then if the sack 4 is s ueezed a portion of the inkwill be forced ack into the bottle only to rush back into the pen again,when pressure upon the sack is removed. By alternately squeezing andreleasing the inksack in this manner after the pen has been filled, abody of ink will be forced back and forth throu h the enlargement 3 insuch a Way as to tl foroughly wash the pen proper. The pen having beenfilled and the pen proper washed, the bottle is turned back to itsupright position and the pen drawn away from the cork, at which time theflexible rubber surrounding the hole 14 will be stretched enough by thetapering upper portion of the enlargement 3 to permit the pen to beeasily disengaged from the cork which will be left in the bottle tofunction there as a cork. If preferred the cork may be used as a s ecialcork and for no other purpose than or -filling fountain pens, but themost convenient way will be to use the cork just the same as though itwere anordinary cork. After the pen has been filled the cap 5 is appliedto it for the protection of the ink-sack 4. I hardly need add that anyfountain pen may be provided with an enlargement 3 to function with acork having a pen-receiving hole functioning like the hole 14 in thecork. The employment, however, ofthe body 2 of a fountain pen for thereception of the ink has an advantage as the body will hold moreink'than a long flexible ink-sack on account of its larger diameter.- Sofar as my present invention is concerned, the flexible ink-sack need beno larger than is required to function as a means for expelling air fromthe pen.

Instead of constructing the cork as shown I in Figs. 2,3, 4 and 5, thenipple 13 might be dispensed with and a pen-receiving hole 15 with aflexible edge 16 formed close to the body 17 of the cork as shown inFig. 6 in which the said hole 15 is formed in the same plane as theflange 18 of the cork. In any case, however, the flexible edge of thepen-receiving hole in the cork stands at a right angle to thelongitudinal axis of the cork so as to be in position to enter theconstriction at the base of the enlargement formed at the forward end ofthe body of the pen.

- I claim The combination with a fountain pen formed at its forward endwith an enlargement and with a constriction at the base thereof andprovided with a flexible ink sack'projecting from its outer end, andwith a cap for .the protection of the said sack; of a cork having apen-receiving hole formed with a flexible edge located in the plane ofthe top of the cork and entering the constriction at the base oftheenlargement at the forward end of the'body of the pen to form anink-tight joint between the pen and the cork when the pen is to befilled, whereby by inserting the enlargement of the pen into thepen-receiving hole of the cork and turning the ink-bottle upside downand manipulating the ink sack the ink may be drawn from the bottle intothe body of the pen.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
